No. You are confused. All those inputs are *already* being injected into the entropy pool. If you don't understand that, you need to read the code more. All echoing crap into /dev/random does is goose the system's entropy estimate so it will give you the _output_ of the pool when it thought it shouldn't yet. Thor
